Data Sheet January 2000 1340-Type Lightwave Receiver s s s CMOS (TTL) link-status flag output Operation at 1.3 µm or 1.55 µm wavelengths Operating case temperature range of –40 °C to +85 °C Applications s Operating at 1.1 µm through 1.6 µm wavelengths and at 155 Mbits/s, 622 Mbits/s, or 1.25 Gbits/s, the versatile 1340-Type Receiver is manufactured in a 20-pin, plastic DIP with a multimode fiber pigtail. Telecommunications: — Inter- and intraoffice SONET/ITU-T SDH — Subscriber loop — Metropolitan area networks High-speed data communications s Features s s s s Description The 1340-Type receiver is designed for use in transmission systems or medium- to high-speed data communications applications at data rates up to 1.25 Gbits/s. Compact packaging, along with wide dynamic range, makes these receivers ideal for both telecommunications and data communications applications. The following three versions of the receiver are available: s s s Backward compatible with 1310 receiver family Space-saving, self-contained, 20-pin plastic DIP Silicon-based ICs Single 5 V power supply operation including photocurrent monitor capability Exceeds all SONET (GR-253-CORE) and ITU-T G.958 jitter requirements Wide dynamic range Qualified to meet the intent of Telcordia Technologies * reliability practices Operates at data rates of 155 Mbits/s, 622 Mbits/s, or 1.25 Gbits/s Positive ECL (PECL) data outputs s s s SONET/SDH compliant with OC-3/STM-1 SONET/SDH compliant with OC-12/STM-4 1.25 Gbits for data applications. s s * Telcordia Technologies is a trademark of Telcordia Technologies, Inc. 1340-Type Lightwave Receiver Data Sheet January 2000 signal amplification, data threshold detection, and PECL data outputs. The incoming optical signal is coupled into the receiver through a 62.5 µm core multimode fiber pigtail. The outer jacket diameter of the pigtail is 900 µm. The receiver can be ordered with the pigtail terminated in an FC/PC, SC, or ST ® optical connector. Other connectors are available on special order. See your Agere account representative for ordering conditions and information. The receiver has differential PECL data outputs and, depending on the version selected, either differential PECL link status flag or complementary CMOS link status flag outputs. The link status flag outputs indicate the presence or absence of a minimum acceptable level of optical input signal. Description (continued) The SONET/SDH versions of the receiver are fully compliant with the latest issue of Telcordia Technologies GR-253- CORE and the most recent issues of ITU recommendations G.957 and G.958. The 1340-Type receiver requires only a single 5 V power supply for operation. All versions of the receiver are characterized for operation over the case operating range of –40 °C to +85 °C at the appropriate data rate for each version. Manufactured in a 20-pin DIP, the receivers use a planar, rear illuminated InGaAs PIN photodetector that allows these receivers to be used at wavelengths from 1.1 µm to 1.6 µm. The photocurrent output of the PIN detector is amplified and converted to a voltage by a silicon amplifier.

Data Sheet January 2000 1340-Type Lightwave Receiver Noise that couples into the receiver through the power supply pins can also degrade device performance. The application schematics, Figures 3—5, show recommended power supply filtering that helps minimize noise coupling into the receiver. The bypass capacitors should be high-quality ceramic devices rated for RF applications. They should be surface-mount components placed as close as possible to the receiver power supply pins. The ferrite bead should have as high an impedance as possible in the frequency range that is most likely to cause problems. This will vary for each application and is dependent on the signaling frequencies present on the application circuit card. Surfacemount, high-impedance beads are available from several manufacturers. Description (continued) To help ensure high product reliability and customer satisfaction, Agere is committed to an intensive quality program that starts in the design phase and proceeds through the manufacturing and shipping process. Optoelectronics subsystems are qualified to Agere internal standards using MIL-STD-883 test methods and procedures and sampling techniques consistent with Telcordia Technologies requirements. The 1340 receiver qualification program meets the intent of Telcordia Technologies TR-NWT-000468 andTA-TSY-000983. Application Information The 1340 receiver is a highly sensitive fiber-optic receiver. Although the data outputs are digital logic levels (PECL), the device should be thought of as an analog component. When laying out the printed-wiring board (PWB), the 1340 receiver should be given the same type of conside.
